Voidly · Global censorship index · CC BY 4.0

Make internet censorship measurable, verifiable, and citable.

Voidly publishes near-real-time evidence of internet blocking, throttling, and shutdown events across 200 countries. Built for journalists chasing a story before access disappears, researchers who need a defensible dataset, and human-rights organizations that have to document harm to act on it.

How we measure

Probes run from 37+ vantage points spanning every continent. Every five minutes each probe checks an 80-domain list across DNS, TLS, HTTP, and BGP layers. Anomalies are scored by an ML classifier, then cross-referenced against three independent measurement projects before being promoted to a verified incident.

What gets measured

DNS tampering
Resolver returns the wrong IP, or refuses to answer.
TLS interference
Handshake interrupted, certificates altered, SNI inspection.
HTTP blocking
Block pages, content rewrites, throttled-to-zero responses.
BGP withdrawal
Networks disappear from the global routing table.
Throttling patterns
Bandwidth deliberately collapsed for specific services.
Full shutdowns
National or regional connectivity dropped entirely.
